Preserving Sensor Location Privacy in Internet of Things
Liming Zhou, Qiaoyan Wen, Hua Zhang · 2012
Internet of Things (IoT) links uniquely identifiable objects (things) to their virtual representations in the internet. Meanwhile, wireless sensor networks are widely used in IoT and various sensors which collect different information containing the identity, status, location of a object or any other business, social or privately relevant information. But some issues related to sensor's location privacy will be paid attention to. In this paper, we focus on protecting the sensor's location by introducing suitable modifications to sensor routing to make it difficult for an eavesdropper to find the original location. And we propose a flexible routing strategy, called Multi-routing Random Walk, which protects the sensor's location. Our strategy can efficiently reduce the chance of packets being detected.
